With Allen out, the team must now turn to rookie first-round pick Vontae Davis, who has never started an NFL game. Davis stepped in for Allen on the left side opposite fellow rookie Sean Smith, who has started all six games at right cornerback.

Davis, 21, finished the game with four tackles. But he missed a tackle of tight end Jeremy Shockey on a 66-yard play in the fourth quarter.

Davis, the No. 25 pick last April, and Smith, who was selected No. 61, were expected to be the team’s cornerbacks of the future.

Miami signed Allen, 31, to a two-year extension in May, with $10 million of it guaranteed.
